After groping, finally can apply the verification code in Laravel 5.1.
Because the English slag five levels, so almost no search for anything useful, so consider on GitHub search verification Code pack!
Note: The package on GitHub often has instructions to use, as the above implementation, generally can be done.
I'm using mews captcha.
Git address: Https://github.com/mewebstudio/captcha above is used in detail.
Hands-on implementation:
--Manually enter the Laravel project directory
--in the corresponding directory, locate the Composer.json file, open it, and add the following statement:
Add statement
{ "require": { .... .... .... " Mews/captcha ":" ~2.0 " }, " minimum-stability ":" Dev "} --Perform composer update, if error, perform composer Self-update before performing composer update
--Find config/app.php open and add the following statement:
1. Open the file, locate the providers entry, and add the following statement
Mews\captcha\captchaserviceprovider::class,
2. Locate the aliases key and add the following statement:
To add a statement:
' Captcha ' = Mews\captcha\facades\captcha::class,
--cmd window to execute PHP artisan vendor:publish
Through all the steps above, you will find the directory under Vendor, and you can use the namespace using Captcha, a mews configuration file captcha.php that has a captcha in config/captcha.php.
--All the steps above are also present in Https://github.com/mewebstudio/captcha!
Let's take a look at the new Vendor/mews directory
We found vendor/mews/captcha/src/captcha.php.
Find the public method and find:
Public function Create ($VAR)---generate a verification code
Public function Check ($VAR)---Determine if the input and verification codes are equal
Public function src ($var)---output img attribute src link
Public function img ($VAR)---output img tag
Where the $var parameter is the corresponding key in the config/captcha.php, which can be:
Default, flat, Mini, inverse represents four styles of verification code! Can be configured for different styles, modify configuration items directly in config/captcha.php
--Example:
1. Configure Routing in app/http/routes.php
Where Captcha/test, which represents the test path, maps Captchacontroller under Public Function Index () {}
Captcha/mews mapping Verification Code output, mapping Captchacontroller under Public Function Mews () {}
2. Create a Controller
In the cmd window, enter directly
PHP Artisan Make:controller Captchacontroller--plain
If the prompt is successful, a new file is generated under app/http/controllers/captchacontroller.php
3. New index () and Mews () methods in app/http/controllers/captchacontroller.php
<?phpnamespace app\http\controllers; Useapp\http\requests; UseApp\http\controllers\controller; Useilluminate\http\request;//referencing the corresponding namespace UseSession; UseCaptcha;classCaptchacontrollerextendsController {/** * Test page*/ Public functionindex () {//$mews = captcha::src (' inverse ');, compact (' mews ') returnView (' Captcha.index '); }/* Create verification code * / Public functionMews () {returnCaptcha::create (' Default '); }}
4. Create a View
Create the Captcha directory under the resources/views/directory, creating a new index.blade.php and probably a layout and style adjustment
<!DOCTYPE HTML><HTMLLang= "en"><Head> <MetaCharSet= "Utf-8"> <Metahttp-equiv= "X-ua-compatible"content= "Ie=edge"> <Metaname= "Viewport"content= "Width=device-width, initial-scale=1"> <title>Learn Laravel 5.1</title> <Linkhref= "{{Asset ('/css/app.css ')}}"rel= "stylesheet"> <!--Fonts - <Linkhref= '//fonts.useso.com/css?family=roboto:400,300 'rel= ' stylesheet 'type= ' Text/css '> <!--HTML5 Shim and Respond.js for IE8 support of HTML5 elements and media queries - <!--WARNING:Respond.js doesn ' t work if you view the page via file:// - <!--[If Lt IE 9]> <script src= "Https://oss.maxcdn.com/html5shiv/3.7.2/html5shiv.min.js" ></script> <script src= "Https://oss.maxcdn.com/respond/1.4.2/respond.min.js" ></script> <!

This time input: Http://your-host/captcha/test view
This is my layout and captcha.
5. Add route to app/http/routes.php
I submit to the background for testing via post
6. The CPT method in TestController is as follows:
<?phpnamespace app\http\controllers\test; Useilluminate\http\request; Useapp\http\requests; UseApp\http\controllers\controller; UseInput, Validator, Redirect, Session,Captcha;classTestControllerextendscontroller{ Public functionCPT (Request$request) { //DD (input::get (' CPT ')); $rules= [ "CPT" = ' Required|captcha ' ]; $messages= [ ' cpt.required ' = ' Please enter the verification code ', ' Cpt.captcha ' and ' = ' Verification code error, please retry ' ]; If you only verify the value of CAPTCHA, you can
Using Captcha::check (Input::get (' CPT ')); returns BOOL
$validator= Validator::make (Input::all (),$rules,$messages); if($validator-fails ()) { returnRedirect::back ()->witherrors ($validator); } Else { return"Verification Code ok!"; } }}
Above, the test is as follows,
Validation error:
Verify correct:
There is no use of the Captcha::check () method, specific analysis of the situation.
